WORKERS AHEAD!

You are viewing the development documentation for the Apereo CAS server. The functionality presented here is not officially released yet. This is a work in progress and will be continually updated as development moves forward. You are most encouraged to test the changes presented.

To view the documentation for a specific Apereo CAS server release, please choose an appropriate version. The release schedule is available here.

SAML2 Authentication

CAS can act as a SAML2 identity provider accepting authentication requests and producing SAML assertions.

If you intend to allow CAS to delegate authentication to an external SAML2 identity provider, you need to review this guide.

SAML Specification

This document solely focuses on what one might do to turn on SAML2 support inside CAS. It is not to describe/explain the numerous characteristics of the SAML2 protocol itself. If you are unsure about the concepts referred to on this page, please start with reviewing the SAML2 Specification.

Federation Interop Evaluation

The CAS project strives to conform to the SAML V2.0 Implementation Profile for Federation Interoperability. An evaluation of the requirements against the current CAS release is available here. It is recommended that you view, evaluate and comment on functionality that is currently either absent or marked questionable where verification is needed.

SAML Endpoints

The following CAS endpoints respond to supported SAML2 profiles:

/idp/profile/SAML2/Redirect/SSO
/idp/profile/SAML2/POST/SSO
/idp/profile/SAML2/POST-SimpleSign/SSO
/idp/profile/SAML2/POST/SLO
/idp/profile/SAML2/Redirect/SLO
/idp/profile/SAML2/Unsolicited/SSO
/idp/profile/SAML2/SOAP/ECP
/idp/profile/SAML2/SOAP/AttributeQuery
/idp/profile/SAML1/SOAP/ArtifactResolution

Metadata Management

Handling and storing SAML2 identity provider or service provider metadata can be done in a few ways. To learn more, please review this guide.

Configuration

Support is enabled by including the following dependency in the WAR overlay:

<dependency>
  <groupId>org.apereo.cas</groupId>
  <artifactId>cas-server-support-saml-idp</artifactId>
  <version>${cas.version}</version>
</dependency>

implementation "org.apereo.cas:cas-server-support-saml-idp:${project.'cas.version'}"

dependencyManagement {
  imports {
    mavenBom "org.apereo.cas:cas-server-support-bom:${project.'cas.version'}"
  }
}

dependencies {  
  implementation "org.apereo.cas:cas-server-support-saml-idp"
}

You may also need to declare the following repository in your CAS overlay to be able to resolve dependencies:

repositories {
    maven { 
        mavenContent { releasesOnly() }
        url "https://build.shibboleth.net/nexus/content/repositories/releases" 
    }
}

The following settings and properties are available from the CAS configuration catalog:

_{The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.}

cas.authn.saml-idp.core.entity-id=https://cas.example.org/idp

The SAML entity id for the deployment.

This setting supports the Spring Expression Language.

org.apereo.cas.configuration.model.support.saml.idp.SamlIdPCoreProperties.

_{The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This flag indicates that the presence of the setting is not immediately necessary in the end-user CAS configuration, because a default value is assigned or the activation of the feature is not conditionally controlled by the setting value.}

cas.authn.saml-idp.core.attribute-friendly-names=

A mapping of attribute names to their friendly names, defined globally. Example might be urn:oid:1.3.6.1.4.1.5923.1.1.1.6->eduPersonPrincipalName.

org.apereo.cas.configuration.model.support.saml.idp.SamlIdPCoreProperties.

cas.authn.saml-idp.core.attribute-query-profile-enabled=false

Indicates whether attribute query profile is enabled. Enabling this setting would allow CAS to record SAML responses and have them be made available later for attribute lookups.

org.apereo.cas.configuration.model.support.saml.idp.SamlIdPCoreProperties.

cas.authn.saml-idp.core.authentication-context-class-mappings=

A mapping of authentication context class refs. This is where specific authentication context classes are reference and mapped to providers that CAS may support mainly for MFA purposes.

Example might be urn:oasis:names:tc:SAML:2.0:ac:classes:SomeClassName->mfa-duo.

org.apereo.cas.configuration.model.support.saml.idp.SamlIdPCoreProperties.

cas.authn.saml-idp.core.session-storage-type=HTTP

Indicates whether saml requests, and other session data, collected as part of SAML flows and requests that are kept by the container http session, local storage, or should be replicated across the cluster. Available values are as follows:

HTTP: Saml requests, and other session data collected as part of SAML flows and requests are kept in the http servlet session that is local to the server.
BROWSER_SESSION_STORAGE: Saml requests, and other session data collected as part of SAML flows and requests are kept in the client browser's session storage, signed and encrypted. SAML2 interactions require client-side read/write operations to restore the session from the browser.
TICKET_REGISTRY: Saml requests, and other session data collected as part of SAML flows and requests are tracked as CAS tickets in the registry and replicated across the entire cluster as tickets.

org.apereo.cas.configuration.model.support.saml.idp.SamlIdPCoreProperties.

cas.client.prefix=

Prefix of the CAS server used to establish ticket validators for the client. Typically set to https://sso.example.org/cas

org.apereo.cas.configuration.model.core.CasJavaClientProperties.

cas.client.validator-type=CAS30

Determines the type of ticket validator that CAS should create from the Java CAS client when attempting to issue in-bound ticket validation calls. Available values are as follows:

CAS10: CAS10 ticket validator.
CAS20: CAS20 ticket validator.
CAS30: CAS30 ticket validator.
JSON: JSON ticket validator.

org.apereo.cas.configuration.model.core.CasJavaClientProperties.

cas.session-replication.cookie.allowed-ip-addresses-pattern=

A regular expression pattern that indicates the set of allowed IP addresses, when #isPinToSession() is cofigured. In the event that there is a mismatch between the cookie IP address and the current request-provided IP address (i.e. network switches, VPN, etc), the cookie can still be considered valid if the new IP address matches the pattern specified here.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.auto-configure-cookie-path=true

Decide if cookie paths should be automatically configured based on the application context path, when the cookie path is not configured.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.comment=CAS Cookie

CAS Cookie comment, describes the cookie's usage and purpose.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.domain=

Cookie domain. Specifies the domain within which this cookie should be presented. The form of the domain name is specified by RFC 2965. A domain name begins with a dot (.foo.com) and means that the cookie is visible to servers in a specified Domain Name System (DNS) zone (for example, www.foo.com, but not a.b.foo.com). By default, cookies are only returned to the server that sent them.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.http-only=true

true if this cookie contains the HttpOnly attribute. This means that the cookie should not be accessible to scripting engines, like javascript.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.max-age=-1

The maximum age of the cookie, specified in seconds. By default, -1 indicating the cookie will persist until browser shutdown. A positive value indicates that the cookie will expire after that many seconds have passed. Note that the value is the maximum age when the cookie will expire, not the cookie's current age. A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.name=

Cookie name. Constructs a cookie with a specified name and value. The name must conform to RFC 2965. That means it can contain only ASCII alphanumeric characters and cannot contain commas, semicolons, or white space or begin with a $ character. The cookie's name cannot be changed after creation. By default, cookies are created according to the RFC 2965 cookie specification. Cookie names are automatically calculated assigned by CAS at runtime, and there is usually no need to customize the name or assign it a different value unless a special use case warrants the change.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.path=

Cookie path. Specifies a path for the cookie to which the client should return the cookie. The cookie is visible to all the pages in the directory you specify, and all the pages in that directory's subdirectories. A cookie's path must include the servlet that set the cookie, for example, /catalog, which makes the cookie visible to all directories on the server under /catalog. Consult RFC 2965 (available on the Internet) for more information on setting path names for cookies.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.pin-to-session=true

When generating cookie values, determine whether the value should be compounded and signed with the properties of the current session, such as IP address, user-agent, etc.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.same-site-policy=

If a cookie is only intended to be accessed in a first party context, the developer has the option to apply one of settings SameSite=Lax or SameSite=Strict or SameSite=None to prevent external access.

To safeguard more websites and their users, the new secure-by-default model assumes all cookies should be protected from external access unless otherwise specified. Developers must use a new cookie setting, SameSite=None, to designate cookies for cross-site access. When the SameSite=None attribute is present, an additional Secure attribute is used so cross-site cookies can only be accessed over HTTPS connections.

Accepted values are: Lax, Strict, None.

org.apereo.cas.configuration.model.support.replication.CookieSessionReplicationProperties.

cas.session-replication.cookie.secure=true

True if sending this cookie should be restricted to a secure protocol, or false if the it can be sent using any protocol.

Configuration Metadata

The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.

Be Selective

This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.

YAGNI

Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.

Naming Convention

Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those that might be presented to the system via an external library or framework such as Spring Boot, etc. When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value.S ettings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the way you intend.

Validation

Configuration properties are automatically validated on CAS startup to report issues with configuration binding, specially if defined CAS settings cannot be recognized or validated by the configuration schema. The validation process is on by default and can be skipped on startup using a special system property SKIP_CONFIG_VALIDATION that should be set to true. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.

Indexed Settings

CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be incremented by the adopter to allow for distinct multiple configuration blocks.

Actuator Endpoints

The following endpoints are provided by CAS:

The following settings and properties are available from the CAS configuration catalog:

cas.monitor.endpoints.jdbc.password-encoder.encoding-algorithm=

The encoding algorithm to use such as MD5. Relevant when the type used is DEFAULT or GLIBC_CRYPT.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.type=NONE

Define the password encoder type to use. Type may be specified as blank or NONE to disable password encoding. It may also refer to a fully-qualified class name that implements the Spring Security's PasswordEncoder interface if you wish you define your own encoder. The following types may be used:

NONE: No password encoding (i.e. plain-text) takes place.
DEFAULT: Use the DefaultPasswordEncoder of CAS. For message-digest algorithms via character-encoding and encoding-algorithm.
BCRYPT: Use the BCryptPasswordEncoder based on the strength provided and an optional secret.
SCRYPT: Use the SCryptPasswordEncoder.
PBKDF2: Use the Pbkdf2PasswordEncoder based on the strength provided and an optional secret.
STANDARD: Use the StandardPasswordEncoder based on the secret provided.
SSHA: Use the LdapShaPasswordEncoder supports Ldap SHA and SSHA (salted-SHA). The values are base-64 encoded and have the label SHA</code> or SSHA</code> prepended to the encoded hash.
GLIBC_CRYPT: Use the GlibcCryptPasswordEncoder based on the encoding-algorithm, strength provided and an optional secret.
org.example.MyEncoder: An implementation of PasswordEncoder of your own choosing.
file:///path/to/script.groovy: Path to a Groovy script charged with handling password encoding operations.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.driver-class=org.hsqldb.jdbcDriver

The JDBC driver used to connect to the database.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.url=jdbc:hsqldb:mem:cas-hsql-database

The database connection URL.

This setting supports the Spring Expression Language.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.user=sa

The database user.

The database user must have sufficient permissions to be able to handle schema changes and updates, when needed.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.password-encoder.character-encoding=UTF-8

The encoding algorithm to use such as 'UTF-8'. Relevant when the type used is DEFAULT.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.secret=

Secret to use with STANDARD, PBKDF2, BCRYPT, GLIBC_CRYPT password encoders. Secret usually is an optional setting.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.strength=16

Strength or number of iterations to use for password hashing. Usually relevant when dealing with PBKDF2 or BCRYPT encoders. Used by GLIBC_CRYPT encoders as well.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.autocommit=false

The default auto-commit behavior of connections in the pool. Determined whether queries such as update/insert should be immediately executed without waiting for an underlying transaction.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.batch-size=100

A non-zero value enables use of JDBC2 batch updates by Hibernate. e.g. recommended values between 5 and 30.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.data-source-name=

Attempts to do a JNDI data source look up for the data source name specified. Will attempt to locate the data source object as is.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.ddl-auto=update

Hibernate feature to automatically validate and exports DDL to the schema. By default, creates and drops the schema automatically when a session is starts and ends. Setting the value to validate or none may be more desirable for production, but any of the following options can be used:

validate: Validate the schema, but make no changes to the database.
update: Update the schema.
create: Create the schema, destroying previous data.
create-drop: Drop the schema at the end of the session.
none: Do nothing.

Note that during a version migration where any schema has changed create-drop will result in the loss of all data as soon as CAS is started. For transient data like tickets this is probably not an issue, but in cases like the audit table important data could be lost. Using `update`, while safe for data, is confirmed to result in invalid database state. validate or none settings are likely the only safe options for production use.

For more info, see this.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.default-catalog=

Qualifies unqualified table names with the given catalog in generated SQL.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.default-schema=

Qualify unqualified table names with the given schema/tablespace in generated SQL.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.dialect=org.hibernate.dialect.HSQLDialect

The database dialect is a configuration setting for platform independent software (JPA, Hibernate, etc) which allows such software to translate its generic SQL statements into vendor specific DDL, DML.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.fail-fast-timeout=1

Set the pool initialization failure timeout.

Any value greater than zero will be treated as a timeout for pool initialization. The calling thread will be blocked from continuing until a successful connection to the database, or until the timeout is reached. If the timeout is reached, then a PoolInitializationException will be thrown.
A value of zero will not prevent the pool from starting in the case that a connection cannot be obtained. However, upon start the pool will attempt to obtain a connection and validate that the connectionTestQuery and connectionInitSql are valid. If those validations fail, an exception will be thrown. If a connection cannot be obtained, the validation is skipped and the the pool will start and continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.
A value less than zero will not bypass any connection attempt and validation during startup, and therefore the pool will start immediately. The pool will continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.

Note that if this timeout value is greater than or equal to zero (0), and therefore an initial connection validation is performed, this timeout does not override the connectionTimeout or validationTimeout; they will be honored before this timeout is applied. The default value is one millisecond.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.fetch-size=100

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.isolate-internal-queries=false

This property determines whether data source isolates internal pool queries, such as the connection alive test, in their own transaction.

Since these are typically read-only queries, it is rarely necessary to encapsulate them in their own transaction. This property only applies if #autocommit is disabled.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.isolation-level-name=ISOLATION_READ_COMMITTED

cas.monitor.endpoints.jdbc.pool.max-size=18

Controls the maximum number of connections to keep in the pool, including both idle and in-use connections.

org.apereo.cas.configuration.model.support.ConnectionPoolingProperties.

cas.monitor.endpoints.jdbc.pool.max-wait=PT2S

Sets the maximum time in seconds that this data source will wait while attempting to connect to a database.

A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout.

This settings supports the java.time.Duration syntax ^[?].

org.apereo.cas.configuration.model.support.ConnectionPoolingProperties.

cas.monitor.endpoints.jdbc.pool.min-size=6

Controls the minimum size that the pool is allowed to reach, including both idle and in-use connections.

Control global properties that are relevant to Hibernate, when CAS attempts to employ and utilize database resources, connections and queries.

cas.jdbc.case-insensitive=false

When choosing physical table names, determine whether names should be considered case-insensitive.

cas.jdbc.gen-ddl=true

Whether to generate DDL after the EntityManagerFactory has been initialized creating/updating all relevant tables.

cas.jdbc.physical-table-names=

Indicate a physical table name to be used by the hibernate naming strategy in case table names need to be customized for the specific type of database. The key here indicates the CAS-provided table name and the value is the translate physical name for the database. If a match is not found for the CAS-provided table name, then that name will be used by default.

cas.jdbc.show-sql=false

Whether SQL queries should be displayed in the console/logs.

If you need to design your own password encoding scheme where the type is specified as a fully qualified Java class name, the structure of the class would be similar to the following:

package org.example.cas;

import org.springframework.security.crypto.codec.*;
import org.springframework.security.crypto.password.*;

public class MyEncoder extends AbstractPasswordEncoder {
    @Override
    protected byte[] encode(CharSequence rawPassword, byte[] salt) {
        return ...
    }
}

If you need to design your own password encoding scheme where the type is specified as a path to a Groovy script, the structure of the script would be similar to the following:

import java.util.*

byte[] run(final Object... args) {
    def rawPassword = args[0]
    def generatedSalt = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

    logger.debug("Encoding password...")
    return ...
}

Boolean matches(final Object... args) {
    def rawPassword = args[0]
    def encodedPassword = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

   logger.debug("Does match or not ?");
   return ...

The following settings and properties are available from the CAS configuration catalog:

cas.monitor.endpoints.ldap.base-dn=

Base DN to use. There may be scenarios where different parts of a single LDAP tree could be considered as base-dns. Rather than duplicating the LDAP configuration block for each individual base-dn, each entry can be specified and joined together using a special delimiter character. The user DN is retrieved using the combination of all base-dn and DN resolvers in the order defined. DN resolution should fail if multiple DNs are found. Otherwise the first DN found is returned. Usual syntax is: subtreeA,dc=example,dc=net|subtreeC,dc=example,dc=net.
